CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 404,195, dated May 28,1889. Application filed March 26,1889. Serial No. 304,794. (No model.)

To all whom it may concern.-

Be it known thatl, JOHN S. HULL, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Can-Soldering Machines; and I do herebydeclare the following to be a full, clear, and exact description part ofthis specification, Figure 1 represents a perspective view; Fig. 2, avertical longitudinal section; Fig. 3, an "end View of the bracket forsupporting the lower end of the can; Fig. 4, a vertical longitudinalsection through the hood and a portion of the base of the can-solderingmachine; and Fig. 5 is a top or plan View of the hood detached.

Reference being had to the drawings and the letters thereon, A indicatesa plate adapted to be secured to a bench by screws passed through theapertures a at the corners of the plate.

B indicates the base of the machine, and is secured to the part A bybolts or screws passed through lugs b. The base is provided with alongitudinal slot, 0, over which is secured an adjustable support, (Z,by bolts 6 e,which pass through the flange f and the slot 0, with theirheads resting upon the under side of the top of the base and their nutsresting upon the outer surface of the flange f. In the support (I issecured a vertically-adjustable bracket, E, by bolt h, passing throughboth and having vertical ELIIIlSt 'i, in which the shaft is issupported. The shaft 70 is provided with a disk, Z, to receive one endof a can, 0, and upon the shaft between the arms a z is located aspring, m, the tension of which is regulated by an adjustable collar, n,to hold the can in position while the heads are being soldered.

On the rear end of the bracket E is a lug, 0, to which an arm or lever,19, is pivotally se cured. The bifurcated end q of the arm p embracesthe shaft 70 and bears against an adjustable collar, 0", for regulatingthe throw of the lever 19, and to the opposite end, s, of the lever isattached apitman or rod,1,which is connected to a treadle, 2, for thepurpose of releasing a can after either one of the heads has beensoldered.

On the outer end of the shaft k is secured a cone-pulley, D, from whicha belt may be conducted to any suitable source of power, or the shaftmay be revolved by-a crank. (Not shown.)

On one end of the base B is secured a bracket, F, which is provided witha slot, 2, through which extends a bolt, u, by which it is secured toand adjusted upon the base. In the upper arm, n, of the bracket issecured a support, 10, which is provided with a socket, y, andoscillates upon the ends of thumb-screws a a, which pass through thesides of the arm n and enter recesses 12 b in the support to adjust thedisk 0, which is supported to revolve in said socket and bears againstthe lower head of a can, and aceommodatesitself to a can which has notbeen correctly centered while it is being revolved for soldering thehead thereto. The vertical oscillation of the support 10 is regulated,and the support held in position to place a can between the two disks,which bear against the can by a thumb-screw, cl, passing through an arm,e, ,on the outer end of the support and bearing against the outersurface of the arm n of the bracket F.

By the adjustment of the brackets E F the machine is adapted to soldercans of various sizes.

In the base 13 is formed a well, f, for solder, into which the can 0projects at the end being soldered and is revolved therein. Asoldering-iron, G, is supported in lugs g g,

projecting up from the surface of the top of V the base B, and isprovided with a counterweight, h', to withdraw the end of the iron outof the solder as soon as a can is removed.

The iron is pressed down into the solder in the well f by the insertionof each can, and it applies the solder to the scam in the usual manner.I i

In front of the solder-well is a transverse slot, i, over which projectsa vertically-adjustable deflector, k, secured under the bracket F, anddirects a portion of the flame from the burner II against the head of acan to heat the head being soldered to the body. of the can. The flamefrom the burner envelops the well f, and is conducted up through alongitudinal. slot, Z, against the lower side of the soldering-iron G,as shown in Fig. 2, and is confined to the front end of the base by atransverse barrier, on.

As a further means for heating the end of the can being soldered anaperture, a, Fig. 4, is formed in the top of the base Ii, and over it isadjustably secured a hood, I, having a short nozzle or tube, 0,projecting therefrom for directing flame against any part of the end ofthe can being soldered. The hood is provided with a slot, 7), throughwhich a lJhlllDb'SCl'OW, q, passes and engages with the top of the base13.

By the use of the deflector 7.: and the hood I the ditliculty heretoforeexperienced in heating the can is entirely overcome, and by the presentarrangement of the soldering iron it is removed from the solder afterthe operation of soldering and cannot become set in the lead as itbecomes chilled, as in the device shown in the patent to which referencehas been made.

Having thus fully described my invention, what I claim is- 1. In acan-soldering machine, the combination of abase provided with alongitudinal slot, a support movable in the slot for the upper end ofacan vertically and longitudinally adjustable on the base, a verticallyad j ustable, rcvoluble, and oscillating support for the lower end ofthe can, constructed to oscillate freely, and a solder bath into whichthe lower end of the can proj ects, substantially as described.

2. In a can-soldering machine, the combination of alongitudii1ally-reciprocating sup port for the upper end of a can, asupport for the lower end of the can, constructed and mounted to revolveand oscillate freely, and a solder bath, substantially as described.

3. In a can-soldering machine, the combination of a reciprocatingsupport for the upper end of a can, a revoluble support if the lower endof the can constructed to oscillate freely vertically with relation tothe solder bath, a vertically-adjustable bracket in which the lowersupport is mounted, and a device for limiting the degree of oscillationof said support and for holding it in position for the insertion of acan between the two supports, substantially as described.

1-. In. a can-soldering machine, a solder bath anda soldering-ironsupported on one side of the bath with its working end normally out ofthe solder, in combination with means for automatically withdrawing theworking end of the iron from the solder when a can is removed, and asuitable burn er, substantially as described.

5. In a can -soldering machine, a solder bath, an automatically-tiltingsolderingdron, and a slot in the base through which said iron is heated,substantially as described.

6. In a cansoldering machine, a solder bath, a slot in front of thebath, and a deflector for directing flame against the end of a can,substantially as described.

7. I11 a can -soldering machine, a solder bath, a slot in front of thebath, and an adjustable deflector secured to the base of the machine,substantially as described.

8. In a can-soldering machine, a solder bath, a transverse slot in frontof the bath, and a longitudinal slot in the rear thereof, in combinationwith a soldering-iron and a burner, substantially as described.

9. In a can-soldering machine, a base having an aperture in it, incombination with a hood secured over said aperture to direct. flameagainst a can, substantially as described.

10. In a can-soldering machine, the combination of a base having afla1ne-armrture therein, an adjustable hood over said aperture providedwith a discharge-nozzle constructed to direct flame against a can, and aburner, substantially as described.

11. In a can-soldering machine, the combination of a base having asolder bath, a soldering-iron, a slot through the base in front of thebath, a slot in the rear of the bath, a hood, an aperture through thebase communicating therewith for directing flame on one side of thebath, and a burner for supplying flame to the several flamc-directin gpassages, substantially as described.

12. In a can-soldering machine, the combination of a base an adjustablebracket, an oscillating can-support in said bracket, and a deflectorsecured by the bracket, and a slot for supplying flame to the deflector,a reciproeatin g support for the upper end of the can, and aburner,substantially as described.

13. In a can-soldering machine, a base provided with a solder bath, asoldering-iron, a slot through which the iron is heated, aflameconflning barrier in the rear of the bath, a slot in front of thebath, and a burner, substantiall y as described.

In testimony whereof I affix my signature in presence of two witnesses.
